The reliability of infrared emission as a galaxy star formation rate tracer Ghent University
Star formation is the most important process in the evolution of galaxies. Hence, to understand the galaxy population reliable star-formation rate indicators are needed. The most widespread tracer is infrared emission, since it is assumed that dust (from which the infrared emission originates) is mostly heated by young stellar populations. However, recent studies challenge this assumption, questioning the reliability of infrared emission as a ...
